6.3 Operation with frequency command [Hz]
Please refer to the instruction manual of the PROFINET IO controller about the way of using it.
For a detailed description of the PROFINET communication, please refer to Chapter 8. The following
is an example of operation with the Standard telegram 1 in the PROFINET communication and setting
A004 to 50 [Hz].
STW1 is the control word. ZSW1 is the status word. NSOLL_A means the setting of output frequency.
NIST_A means the actual output frequency.
[Setpoint (PROFINET IO controller -> PROFINET IO device)]
① Setting STW1 to 0x0406.
② Setting STW1 to 0x0407.
③ Setting STW1 to 0x047F.
④ Setting NSOLL_A to 0x4000 (100%).
⑤ Setting NSOLL_A to 0x1000 (25%).
⑥ Setting NSOLL_A to 0x0 (0%).
⑦ Setting NSOLL_A to 0xC000 (-100%).
⑧ Setting NSOLL_A to 0x0 (0%).
[Actual value (PROFINET IO device -> PROFINET IO controller)]
⑨ Stopping state, PROFIdrive transition to “Ready For switching On”.
⑩ Stopping state, PROFIdrive transition to “Switching On”.
⑪ Driving with 0x0 (0% : 0[Hz]) state, PROFIdrive transition to “Operation”.
⑫ Accelerating in forward direction, “XXXX” indicates NIST_A during acceleration.
⑬ Driving at a constant speed state, NIST_A is equal to 0x4000 (100% : 50[Hz]).
⑭ Deceleration state, “XXXX” indicates NIST_A during deceleration.
⑮ Driving at a constant speed state, NIST_A is equal to 0x1000 (25% : 12.5[Hz]).
⑯ Deceleration state, “XXXX” indicates NIST_A during deceleration.
⑰ Driving at a constant speed state, NIST_A is equal to 0x0 (0% : 0[Hz]).
⑱ Accelerating in reverse direction, “XXXX” indicates NIST_A during deceleration.
⑲ Driving at a constant speed state, NIST_A is equal to 0xC000 (-100% : -50[Hz]).
⑳ Deceleration state, “XXXX” indicates NIST_A during deceleration.
